IiFayibha zeBasalt ziphucula ukuchasana kweCarbonation yeConcrete

I. Inkqubo yesenzo se-anti-carbonation: i-multi-scale synergistic optimization
1. Ubume bepore kunye nokuthintela ukuqhekeka
   Iifayibha zebasalt thintela iintanda zeplastiki zangaphambili ze-shrinkage kwikhonkrithi (i-30% -50% yokunciphisa ububanzi) kunye ne-block CO₂ iindlela zokusabalalisa ngokusasazwa kwe-mesh-dimensional-dimensional. Iimveliso ezixineneyo ze-hydration ezenziwe kwi-fiber-matrix interface zinokunciphisa umlinganiselo we-pores ezinobungozi (> 100 nm) ukusuka kwi-18.6% ukuya kwi-12.3%, ukunciphisa kakhulu ukugqithiswa.

2. Ukumodareyithwa kwamanzi kunye Ikhemikhali intsebenziswano
Ifayibha umphezulu uburhabaxa ikhuthaza CSH gel heterogeneous nucleation, ukukhawulezisa reaction hydration, 28 iintsuku isidanga hydration lonyuke nge-8% -12%. Xa kudityaniswe nemixube yeeminerali (umzekelo, umsi we-silica), isiphumo sothuthu lwentaba-mlilo esidityaniswe ne-fiber fracture-limiting effect yehla i-porosity iyonke ngama-40%, kwaye umlinganiselo weepores ezingenabungozi (

II.Umsebenzi wobunjineli kunye neenzuzo zoqoqosho
1. Ubomi bendlela bandiswa kakhulu
Ukwenza okuphezulu IFayibha yeBasalt I-asphalt ikhonkrithi ephandwayo kwaye iphuhliswe yiYunivesithi yaseYangzhou, ukuxhathisa ukurutha kwanda nge-20% -40%, ukudinwa ukuchasana nokuqhekeka kwanda ngamaxesha angama-2-8, umjikelo wokulondoloza wandiswa ukusuka kwiminyaka eyi-3-5 ukuya kwi-6-8 iminyaka, ukugcinwa kweendleko zexesha elide kuncitshiswe kakhulu.

2. Ukusebenza okuphuculweyo kwekhonkrithi esetyenzisiweyo
Uphando lubonisa ukuba xa i-recycled aggregate concrete (RAC) ixutywa ne-2 kg/m³ ye-basalt fibers, ubunzulu be-carbonation buncitshiswe nge-41% xa kuthelekiswa nekhonkrithi eqhelekileyo esetyenzisiweyo, kwaye okona kuxhaphakileyo kwekhabhoni kuphunyezwa nge-50% yereyisayikilisheki yereyisayikilisheli edityanisiweyo yokutshintsha.

III. Iindlela zexesha elizayo kunye nemingeni
1. Uphando oludibanisa imimandla emininzi
Isidingo sokuphonononga ngakumbi ukusebenza kwexesha elide phantsi kwe-carbonation-chloride yokudibanisa ityuwa-umthwalo wetyuwa, idatha yokuqala ibonisa ukuba izinga le-carbonation ye-fiber concrete phantsi kwamaxesha angama-0.5 umthwalo wokugqibela usephantsi kwe-28%.

2. Ukudityaniswa kokubeka iliso okukrelekrele
Ukufakelwa kwe-carbonation-sensing optical fiber kunye ne-fiber network, ukulandelwa kwexesha langempela le-carbonation front (ukuchaneka ± 0.1 mm), ukubonelela ngenkxaso yedatha yokukhusela ukukhusela.

I-basalt fiber ibonelela ngesisombululo semigangatho emininzi yokumelana nekhonkrithi yekhabhoni ngokusebenzisa i-microstructure optimization kunye nokuphucula ukusebenza kwe-macro. Ngokuphuculwa kwenkqubo esemgangathweni kunye nokwenziwa kwezinto ezintsha zobuchwepheshe, ukusetyenziswa kwayo kuya kwandiswa ukusuka kwiindlela kunye neebhulorho ukuya kubunjineli baselwandle kunye namanye amacandelo, ukukhuthaza ukuqina kweziseko zophuhliso ukuya kwixesha elitsha.
